The settings apply to CentOS
In SSH /Putty
1. We copy the file of eth0 interface and we rename it: eth0:0. This will enable us to edit the file:
2. We can now edit the eth1 file to replace the IP. You can either use nano or vi(m):
First of all, replace the device name, then the existing IP by the fail over/ additional one that you have received by email:
The broadcast is always the same as the additional ip you wish to add.
3. Now you just have to assemble the new interface that we have just added:
At the time of reboot, the interface will automatically be assembled.
4. IP test
If operations 1 to 3 have been correctly carried out, the IP shown in eth1 file must be pingable from another machine and answer to the requests.
If you have several additional IPs; you can renew the operation by using eth1, eth0:2 and so on.
If after handling, your IP doesn’t answer to the pings, please contact our support.
